    Lumens are a good engineering term - useless for discussions with other than lighting experts as you explained quite nicely!

            Is your source regulated?

            If the source is regulated, any 12VDC frexible strip will do very well. The store I work in sells the heck out of it 'cause it is cersatile, dimmable and easy for beginners to work with.

              The CRI index for the husband of a tetrachromat is still not good enough.

              My next job will be to create a RGB 3 channel LED circuit board with 3 or 6, 1 watt LEDs so I can mix the colors to get true white, that dims to an amber color, like incandescents do.

                There is a problem, regulators use power.

                  Then with that logic, I assume that if there is no regulation then replacing the blown LEDs is .....acceptable? Not for my money!

Probable not stated in terms laymen will catch or understand, not does the article point it out th efficiency is in a range of 24-50 l/w. To put that in terms most can understand is it is only slightly better than a plain ole incandescent Edison bulb, and less than CFL. It falls way short, 24 to 50% of fluorescent tube types which come in @ 100 l/w.

                        Looks a little to blue for me.. I would use ones that are closer to white . but not those yellow looking "soft white".

                          By far i'm a lot happier than the CFL Bulbs

                          CFL Bulbs = HOT inverters and FIRE maybe? = YUCK!
                          I have both and lost two LEDs due to overheating - probably cheap ones (not cheap to buy unfortunately).

                          I have yet to lose a single CFL the past four years - proper installations in two new homes. All T5 florescent lamps are doing fine. Incandescents only used for motion activated lamps and have replaced one bulb there.

                          I plan to install driveway illumination (very low level) using LED fixtures in the near future - will be interesting to monitor them for power consumption and all.

                            What are you talking about? Nothing should be hot.

                              Well mabe in theory nothing should be hot.. but I have felt some cheap CFLs and the base is too hot to touch.. I have found Philips ones to run the coolest.
